Hi I had the same problem with my headset. Apparently, you need to go onto the razer website and enter the verification code in the headphones you can check the instruction manual. then they will give you the code. Enter the cide choose your speaker and then you can activate 7.1surround sound. Hope this helps!

Hi Lizr1.

I'm here to help. Please check if the headset model is listed here. If so, you can try to request an activation code at this link. Should you need additional assistance, please PM me your device serial number so I can verify its model and check if it supports THX Spatial Audio. All the best!
